Metal Converter Update

Added 2017-10-29 23:26:14 +0000 UTC

Hey there,

The metal converter on RegalGoblins was broken. Like, super broken. It didn't make any sense. I've fixed it now.

Link: http://regalgoblins.com/converter.html

For those interested in the inner workings of the conversion process, it goes like this. There are 2 key values: The materials cost, and the skill cost.

Materials cost: Since we use copper/brass/bronze* as our default metal in Arcadia, things cost 50cp / lb when made of copper or an alloy of it. We adjust for the relative density and value of the metal we're converting to. So if silver has 1.2 times the density of copper and has 10 times the value of copper, we will multiply the material cost of an item that is to be made of silver by 12 (10 x 1.2).

Skill cost: The raw skill value** of an item is its total value minus the materials cost. So a dagger (1lb, 200cp) has a raw skill cost of 150cp (200cp - 1 x 50cp). To get the actual skill cost, we multiply the raw skill by the square root of the metal value*** to reflect the markup of the smith (who rounds fractions up). So if we're making a silver dagger, the actual skill is going to be valued at 150 x √10 = 475cp.

Total cost: Add materials cost and skill cost. A silver dagger's value would be Material (50 x 12 = 600) + Skill (150 x √10 = 474) = 1075cp.

All this assumes you are converting from a copper or copper alloy base to another metal, and assumes the entire item is made of that metal. That means things like spears are awkward to convert. A spear weighs 5lb, but most of that weight is in the haft, so you might convert a spear as if it had a weight of 1lb. While making a calculator that would account for the other parts of an item that aren't metal is possible, it doesn't seem worth it since you then have to track the weight of items by their sub parts.

Here are some sample items at their regular price, their silver price, and their iron price:

*For simplicity reasons, copper, brass, and bronze are all interchangeable and all have the same value and density. Similarly iron and steel have the same value and density.

**Minimum raw skill value of 50cp

***Minimum skill markup for non copper/brass/bronze items is 10%
